Summary:                    COVERAGE_EXTRA_FLAGS not respected when coverage is
run from ctest script
Description: 
I configure my project with <pre>-DCOVERAGE_EXTRA_FLAGS:STRING="-l -p"</pre>.
Now if I run the coverage with <pre>ctest -D ExperimentalCoverage -VV</pre> I
can see that the arguments "-l -p" are passed to the gcov executable.
If I invoke the coverage with the <pre>ctest_coverage()</pre> command in a ctest
script which I run with <pre>ctest -S script.cmake -VV</pre> I see that the
arguments are not passed to gcov, even the default argument -l is not passed.


Additional Information: 
Running both described variants with the --debug option I see that when running
without the script the function <pre>cmCTest::UpdateCTestConfiguration()</pre>
is called and all values from DartConfiguration.tcl are read.
Running with the script the function
<pre>cmCTest::UpdateCTestConfiguration()</pre> is left early and the values from
DartConfiguration.tcl are not read, in this case especially CoverageExtraFlags
which holds the gcov arguments.

The variable <pre>COVERAGE_EXTRA_FLAGS</pre> was introduced with commit
http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=2f309cba455d0a946e935f66a53561ba64717faf

To fix this bug I think and addition to
<pre>cmCTestCoverageCommand::InitializeHandler()</pre> needs to be made:
<pre>this->CTest->SetCTestConfigurationFromCMakeVariable(this->Makefile,
"CoverageExtraFlags", "CTEST_COVERAGE_EXTRA_FLAGS");</pre>
